One feature I'd like to see in C (or any other language) is the
ability to bind an arbitrary C legal name to an arbitrary machine
specific external. For example, if I wanted the machine symbol
"foo-bar" I could do something like...
equivelence int foo_bar "foo-bar";

At the time the syntax was (approximatly) "#equivalence foo_bar foo.bar", and later "#pragma equivalence foo_bar foo.bar". I believe this was in response to the standardization effort, but I wasn't the acceptor's bug-fix man by then, so I don't know.... --dave (God's Chosen Operating System is alive and living on the Riviera) c-b -- David Collier-Brown. {mnetor|yetti|utgpu}!geac!daveb Geac Computers International Inc., | Computer Science loses its 350 Steelcase Road,Markham, Ontario, | memory (if not its mind) CANADA, L3R 1B3 (416) 475-0525 x3279 | every 6 months.

We also have #pragma alias foo_bar foo-bar so that the object named by foo_bar is given another name, which can be used by a module written in a different language (or by the C library, to avoid conflicts with user defined routines).

I used it once to get ahold of the `BLANK COMMON' area used by some Fortran routines. If I remember correctly a typical use might be something like: float p[500] $name(".BLNK."); -- John Sambrook Internet: john@nsr.bioeng.washington.edu University of Washington RC-05 UUCP: uw-nsr!john Seattle, Washington 98195 Dial: (206) 548-4386
